IMPROVEMENT IN CHURNS.

Specification forming part of Letters Patent No. 55,320, dated June 5,1866.

To all whom it may concern:

Be it known that I, DAVID MARSHALL, of Genoa, in the county of Cayugaand State of New York, have invented a new and useful Improvement inChurn-Powers and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theannexed drawing, making a part of this specification, in which thefigure is a front elevation of the whole machine.

A is the base-plate or foundation. It may be made in any convenientmanner, and .must be made so as to support the churn and posts of theframe and thick enough to receive the balance wheel below the uppersurface, as shown in the figure, in which the dotted lines represent apart of the plate removed to show the balance-wheel.

B and B are posts fastened upon the baseplate. Their use is to supportthe cross-pieces, (J and D, also to support the driving-wheel axle.

O is the lower cross-piece. It must be placed high enough above thechurn to allow the attachments to the dasher to move up and downwithouttouching. It has a hole through it for the spindle H to pass through,and slide-box for the slide J to pass through.

D is the upper cross-piece. It also has a slide-box, and journal box tosupport the upper end of the spindle.

E is a balance-wheel. It is fastened to the lower end of the spindle F.It should be below the upper surface of the base-plate to be out of theway.

F is the spindle. It is made long enough to extendfrom near the bottomof the base-plate to the upper cross-piece. At the lower end it shouldbe supported upon a pivot or step to keep it in position and preventfriction. The upper end is supported in a journal-box, and should have aset-screw applied to the upper end to keep it from moving up or down. Ithas the cam-wheel I securely fastened to it on the part between thecross-pieces.

G is a driving-wheel of bevel-gear of any size required to give theproper motion. It is supported by an axle that is supported in one ofthe posts 13.

H is a pinion. It is fastened to the spindle,

and is driven by the wheel G.

I is a vertical cam-wheel. It ismade any size to give the requiredmotion to the churndasher. It is securely fastened to the spindle Fbetween the cross-pieces, as shown in the figure.

J is a vertical slider or sliding bar. It is held in position by boxesin the cross-pieces O and D. It has a projection at the lower end with ahole through it for receiving and holding dasher-clasps. It is actuatedby means of pins or studs that project from the side toward thecam-wheel, one being above and the other below the rim of the wheel. Onthese studs are rollers placed to prevent friction. These rollers may bemade of metal, but to prevent noise they may be made of leather orindia-rubber.

K is a sleeve or dasher-clasp. It is made to pass through the projectionat the lower end of the slider J. end, and has two vertical slits fromthe upper end down as far as the clasp L can go for the purpose ofyielding to the screw in the clasp, so that the churn-dasher may befirmly clasped at any required point or place.

L is a sliding ring made to fit upon the sleeve K. It is provided with athumb-screw that is used to fasten the ring where required.

M and M are elastic rings placed upon the sleeve K, one above and onebelow the projection of the slider. The use of the rings is to preventnoise when the dasher is given less motion than the slider. To use thesleeve and clasp at the commencement, put the sleeve up, and then placethe ring L down firmly upon the projection, with theelastic rings M inplace, and with the thumb=screw fasten it, and the whole motion of theslider will be given to the dasher; but when less agitation is requiredraise the ring L up on the sleeve as far as required, and the distanceit is raised will be the loss of motion to the dasher. By these meansthe motion of the dasher may be changed, and the dasher maybe raised orlowered so as to work at the top or bottom of the cream, as required.

N is the churn-staff. O is the churn, of any ordinary construction.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The arrangement of the spindle F, camwheel I, and slider J, when madesubstantially as specified and used for the purpose set forth.

2. The sleeve K, ring L, and elastic rings M and M, when made andapplied as herein specified. DAVID MARSHALL. Witnesses:
